TO ALL WHOM IT MAY CONCERN:

Be it known that I, BRADFORD G. H. HATIIAWAY, of Rock Stream, in the county of Yates, and State of New York, have invented a newwand useful Improvement in Harvesters; and I do, hereby declare that the following is a full, clear, and exact description of the same, reference being bad to the annexed drawings, making part-offthis specification, in which-- I Figure 1 isa perspective view.

The same letters are employed in all the figures for the indication of the same parts.

These improvements relate to the harvester described in Letters Patent issued to me on the 28th day of May, A. 13.1867. V i i The nature of the improvements will appear from the following specification and claims.

Reference is made to the said original Letters Patent for a description of such parts as may be common to both, and which are fully described therein.

A A are the wheels, of which the former is the driving-wheel. These wheels run on a revolving axle, B. C is the tongue. D, a spherical case enclosingthe mechanism for driving the cutters. E, the drivers seat. F is a pawl in a recess of'the hub of the driving-wheel, working into a ratchet in the recess in the collar F, fastened to the axle, the purpose being to turn the axle only when the drivingwvhel is moving forward. These parts are all set forth in the original patent. A clutch, G, is attached to and revolves with the axle, but so attached that it may slide longitudinally on the axle, to throw the cutting-mechanism into or out of gear. This is done by a yoke, G, fitted into a groove around the clutch. The stem of this yoke extends through the spherical case, and is attached to a lever, G which is pivoted to thehuh of the case. G is a bell-crank, pivoted by lugs to the lever G having an arm, G, with anotch on it, which, entering a hole through the case, may be usedfor holding the clutch in gear, being pressed downwards by a spring, G placed behind the bellcreuk. When the clutch is drawn back by the lever, the cutting-mechanism will not be operated. It may he put in motion by pressing forward the clutch until it connects with a corresponding clutch on the hub of the radial arms H, shown at H. These radial arms turn .on or with the axle, accordingly as they are engaged or disengaged by the clutch G. On their outer ends they carry the three planet-wheels I, which revolve on wrists projecting from the sides of the radial arms. Theseplanet-whecls revolving with the arms are caused to turn upon their respective axes by the internal gearing D, placed on the inside of the spherical case D. They com municate motion to the spur-pinion K, cast on the back of the bcvchwheel K, which, turning on the axle, gives motion to the bevel-pinion L, on the shaft L, which, extending through the tubular attachment D of the case D, carries the driving-crank L The pitman M, attached to the crank, drives the knives i on the finger-bar N.

The shoe and tongue are attached to the tubular extension D of the case, all of which is set forth in said original Letters Patent, as is also the arrangement of parts for adjusting the height of the cut.

The following arrangement of parts is intended to allow the finger-hat to be folded back parallel with the machine: 0 is the shoe, resting on-a wheel, 0, and hinged to \vrists'on the braces, at'O 0 O is a cap, c0vering the end of the finger-bar N, which is made to turn back in a horizontal plane on a bolt passing through the cap, shoe, and finger-bar. The connecting-rod M is attached to a slide, M, running on guides formed in the cap 0 to which is fastened thc'cutter-barN. The end of the finger-bar is rounded, and has a notch. to receive the point 1, extending from a spring,-.P, fastened to the side of the shoe. This point holds the cutterbar firmly in place. It may be detached by means of the cord or chain P and lever I, when the cutter-bar may be folded back against the wheel, swinging in a horizontal plane. Q is a lever, with a hook at one end to projeot under the hrace, the other end bearing against the cuttenbar. This projecting point prevents the shoe and cutter-bar from turning vertically when the cutter-bar is extended, but, as the finger-bar turns, the lever is -forced back, disengaging the point, so that, when the tingor-bar has been turned back parallel with the wheel, the shoe may be turned on its pivots, and the points of the fingers turned upwards, thus placing them in convenient position for shipping the machine, or moving it when not at work.

Instead of the spring I, I propose to use a dog, shown at :0 in fig. 5, having a shoulder fitting against a corresponding shoulder on the end of the. finger-bar. The dog is attached directly to the shoe by a belt, or by bending the end to pass through the shoe and form a pivot. g

The stirrup S, fig.'21, is hung on the hub of the wheel A, which turns within it, and is used for suspend ing the rear of the platform when the machine is used as a reaper.

What I claim as my invention, and desire to secure by Letters Patent, is-

1. The arrangement of the sliding clutch Gr, yoke G, lever G bell-crank G stem G, spring G and spherical ease D, substantially as described. v

2. The combination of a shoe so attached as to oscillate laterally, and a finger-bar so hinged thereto that the shoe remaining stationary, the finger-bar may be folded back in a horizontal plane, to' stand parallel with the line of draught, substantially as described.

3. The combination. of the shoe 0, hinged finger-bar N, spring P, or its'equivalent, and lever Q, substantially as set forth.

In testimony whereof, I have signed my name to this specification in the presence of two subscribing witnesses.
